A New Wasp Parasitoid of the Fall Webworm

Researchers in China have discovered a new wasp species that may possibly be used to control fall webworm (Hyphantria cunea), an invasive pest that causes severe damage to forest and ornamental trees in Europe, Asia, and North America. The wasp is described in an article in the Annals of the Entomological Society of America.

Trichospilus albiflagellatus is a tiny wasp (1.4–2.3 mm) that is easy to mass rear, according to the authors. The specific epithet — albiflagellatus — is derived from the whitish antennal flagellum of the females.

“Our results indicate that the new parasitoid species is easy to mass rear,” the authors wrote. “Thus, we propose that the new species T. albiflagellatus could be a promising biocontrol agent for H. cunea.”
